S4E5 Members Only

The girls set their sights on becoming members of the Justice Friends, a superhero organization, but first, they need to demonstrate their abilities through challenges that assess strength, speed, and intelligence. Unfortunately, the group has a major drawback: it excludes "little girls" and is predominantly male. Just when it seems all hope is lost, an enemy launches an attack on the organization, prompting the girls to step in and save the day, proving their worth despite the organization's biases.
